odd duplicate size
 

SuperDuper! seems to be working well but please can I ask for reassurance about something.

I have begun using three scripts with SuperDuper! 2.7 for the first time. They are:

- Exclude system cache files.dset
- Exclude system temporary files.dset
- Backup - all files.dset.

The result is:

Source
Used 511 GB

Target
Used
171 GB.

The duplicate is bootable and all folders seem to be there. Backup - all files is set to ignore the Downloads folder, which is 153 GB. (Other users' Downloads folders are empty.)

Can the system cache files and temporary files account for the missing 187 GB?

Unlikely. The log should indicate what's generally excluded. Did you look at those folders?
